In my line of work, there is nothing more explanatory than show and tell.

Here is a photo of some work I performed on a client's knee that was not functional after the surgery she had. She had constant pain in her knee, and had difficulty in bending down and doing very simple exercises. After only two sessions of lymphatic drainage and light massage to loosen the scar tissue (scar), we could see the knee cap (patella) where it was lost in the swelling beforehand, and there was definite improvement in her knee. She felt she could move her leg easily, the swelling decreased and the mobility restored was enough to allow her to go back to the gym and work out in a regular manner. There may be more sessions required in the future but after two, she was already very pleased. Moral of this story: sometimes after surgery, the area requires a little more work in order for the body to adapt to the physiological change. With a little help and patience, there is definitely a chance that you can get back into doing the activities that you were doing before the event happened that caused the surgery.
